- a citizen of the' United States',v residing fat Laporte, in thecountyof Laporte fand State.

P5 of ndiana, have invented certain new and usefulimprovements inMetalliclDoors, of which the .followingis a specification. A

The invention relatesl to metallic doors,

door so constructed that the' panel, svtile's, rails and molding areinterengagedunder spring tension in the materials'- such av ina-nnerthat no noise making vibrations cany i Voccur becauseI of loosecont-acts inthe parts. 15

Also to'provide the `stile or rail WithA longitudinally disposed ribsadjacent veac-hside oit they panel, with which ribs` flanges cark v3Qried by the `outer ends of the molding engage and cooperate in such a(manner as to,

torce the sides ofthe molding intoeloseand binding engagement ivith thepanel7V thereby preventing noise incident to`-vibration vof the parts. YY t llVith the above and other objects injview ,the invention residesyinthe combination Y and arrangement of parts as hereinafterset ,t'oithyshown in the drawings',describedandk '40, claimed7 itbeingunderstoodthatclianges V,inthe precise embodiment ofthefini'fention may be` made Within the scope'fofwhat is f Withoutdeparting tronir` the spirit* claimed VVof thej'invention.

bers adapted to rest on thev innei sides d kof the rail or lstile Vasthe case may be,

and are provided with channels 2, which receive the beadsy 10u, Vtherebypreventing outward movement of thefcfiangesmll, and

` at the same` time piovic'ling means whereby t-he inner faces 2Q willbe heldin close and eraby-first secured in `the molding, after which thestiles and rails l,

2' and 3, are placed in position, then the stiles and rails are securedtogether as `at in anysuit# kable manner, ksuoli for instance aswelding.

Froiiithc above itiwill be seen that a metallic door is provided, whichkmay be simply assembled, the parts so constructed that they arefrictionally held under tension,fthereby preventing rattling or noiseVlincident to vibration.. lt will also be seen that the welding-pointsare concealed with#v if in the molding, thereby obiiatingl the expense'incident to linishing the metal adja cent the welding point, and that`the miters of the .molding may be easily reached 'from the inside,thereby allowing the miterjoint to be fused, soldered or otherwisesecured on the inside, and obviating the'necessity ot finishing thejoints, which is now Vthe prac.h tice.' on the outside.
